China’s definition of what is their territorial waters is completely unrelated to internationally accepted borders. If you are unaware of the last ~10 years of territorial bullshit in the seas outside of China I cannot summarize it in an internet comment, please read some articles and watch some documentaries. China’s behavior is shocking, murderous, unhinged, and divorced from reality.

Edit: also as a Finn you should be proud of your correct usage of whether instead of weather because English is stupid and you wrote it correctly.
